SOTH probably has more experience than anybody on here drag racing with regular street tires and a stick shift. His words on this subject, whatever they might be, should be taken as gold LOL....
Good point SOTH on mentioning full tank. I didnt think to mention that. The full tank,tool box and whatever else you have in the trunk, adds to rearward weight bias, which is what I was trying to help him to achieve with sandbags. Look for some of the no prep big power guys with weight bars in the back too.
I actually try to run about 3/4 full tank too, I noticed that with the stock fuel pickup location if fuel level gets below about 3/8s of a tank or so is that the fuel pump pickup can become uncovered breifly if launching to try for 1.50s 60 foot time.

I run about the same tire pressure as your boost pressure, 26 I think, whatever it says on the door jamb.
I launch in 1st, at 5 to 6k, revving without launch control. Wet burnout works well with these crappy continental tires. Trunk full of tools, snacks, and a full tank. I can pull 1.7 60's.
Maybe you should watch one of my videos. 4.3 sucks with a 6 speed, but not enough to start in 2nd.
Soth's quick *** Miata

Yes, fuel all on the rear wall of the tank with extreme acceleration. I can finally rip down to empty, now that I picked up a hydramat pump sock, long side going up the back wall, works great.
I have several reasons for not using launch control, but... Mostly because I am old, just been launching sticks for too long to change now. I just can't seem to make a decent pass with any of that LC/FFS **** on.
